The breeds, which will compete in the Terrier and Hound groups respectively, gained full recognition from the American Kennel Club in 2012. They both had their first go-round at the National Dog Show in November, but this is their inaugural appearance at the prestigious Westminster competition.

You may remember that at last year’s show, six breeds made their Westminster debut. (You can read more about them in the gallery below.)

8 Relative Newcomers to the Westminster Dog Show

2013 Debut: Russell Terrier

The small and confident Russell Terrier excels at vermin hunting, much like many of her terrier relatives. You may know her by her more colloquial name: the Jack Russell Terrier.

She's very similar to the Parson Russell Terrier, who was first recognized by the American Kennel Club in 1997. But the two dogs are different in body structure and height (the Russell Terrier has shorter legs), so American and European kennel clubs consider them to be separate breeds.

2013 Debut: Treeing Walker Coonhound

The Treeing Walker Coonhound is the fourth coonhound to win full AKC recognition in the past three years. As his name implies, this competitive canine was bred to track and tree wild raccoons.

He has a glossy, tricolored coat that's dense enough for protection. The AKC describes this breed as "a fast, sensible hunter that locates its quarry quickly and has superb endurance and treeing ability."

2012 Debut: American English Coonhound

A descendant of the English Foxhound, the American English Coonhound is known for speed and endurance, and was typically used for fox and raccoon hunting. This breed is a member of the Hound Group.

Westminster Kennel Club

2012 Debut: Cesky Terrier

A less excitable member of the Terrier Group, the Cesky is one of the Czech Republic's national breeds and was developed to hunt small game by working in packs. Don't confuse "less excitable" with "inactive," though — this breed never stops needing exercise and socialization.

Westminster Kennel Club

2012 Debut: Entlebucher Mountain Dog

A member of the Herding Group, the Entlebucher Mountain Dog is a native of Switzerland and the smallest of the four tricolored Swiss Mountain Dogs. He's a very energetic dog known for his loyalty to his master.

Westminster Kennel Club

2012 Debut: Finnish Lapphund

The Lappie, as he's called, was originally used for reindeer herding in northern parts of Scandinavia and sports a double coat that makes hot weather unbearable. It's not just his face that's sweet like a teddy bear; the breed is a friendly and sociable member of the Herding Group.

Westminster Kennel Club

2012 Debut: Norwegian Lundehund

The Norwegian Lundehund, a member of the Non-Sporting Group, is nicknamed the “Puffin Dog” due to his use in hunting puffin. This breed is beautiful and loyal but can be a challenge to own.

Westminster Kennel Club

2012 Debut: Xoloitzcuintli

Despite its recent inclusion in the show, the Xoloitzcuintli (pronounced show-low-eats-queen-tlee if you're ambitious, or you can just go with Xolo) is one of the world’s older breeds and is said to be the first canine of the Americas. Central American and Mexican traditions state that the breed wards off evil spirits and intruders, but even without those attributes, this member of the Non-Sporting Group is an excellent companion dog and comes in three sizes.

Over the next few years, the club added about a dozen dogs each decade until the 1930s — which saw an explosion in the number of fully recognized breeds. In the 1920s, the AKC admitted eight breeds; in the 1930s, 22 breeds became fully recognized. In the decades after that, new additions dwindled to somewhere between three and eight new breeds every 10 years.

Then in the 1990s, the club offered full recognition to 16 breeds. And it kept on growing. From 2000 to 2009, it admitted 19 breeds. In the beginning of this decade alone (from 2010 to 2012), the club has already inducted 11 breeds.

If you did your math right, you’ll have calculated that the Russell Terrier and the Treeing Walker Coonhound are breeds No. 176 and 177 in the American Kennel Club. That’s a lot of competition to handle at their first Westminster, but we bet they’re up to the challenge!
